THE PERFORMANCE OF A CATALYST DEPENDS ON:
- Contact area, porosity;
- Time of contact with the gases to be treated;
ZELDOVIC MECANISM FORMATION OF NITROGEN OXIDES
N2 + O → NO + N
N2 + O2 → NO + O
N + OH → NO + H
High temperatures and high concentrations of O2 result in the exponential increment of the production of nitrogen oxides of thermical origin.
